Initial charge tips
With the initial charge, the control will not
yet be able to detect which battery type has
been installed. Keep charging the batteries
until the display shows a full charge (batteries may still not be completely charged).
The next charging process will have an accurate display and charge power and the
batteries will be fully charged.
Use the appliance until the deep discharge
protection switches off the brush motor and
the turbine after the initial charge of the battery. This procedure is necessary to adjust
the battery indicator. Only then the correct
battery status is displayed.
Insert the plug of the connecting cable
into the socket. The charging process
will start.
